Answer:
The correct answer is option (2) "increased exposure to ultraviolet light".
Step-by-step explanation:
The ozone shield or the ozone layer is a region of the atmosphere comprised of high concentrations of ozone that absorbs most of the Sun's ultraviolet radiation. Therefore, damage to the ozone shield will cause increased exposure to ultraviolet light over the United States. This could cause harmful consequences such as an increase of cases of skin cancer, sunburn and cataracts.
